Answer:
The force of gravity can cause erosion by;
- pulling rocks and other particles down the side of a mountain or cliff
- it can cause landslides which significantly erode an area.
"Ammonification" is NOT a process that drives the carbon cycle.
<u>Option: B</u>
<u>Explanation:</u>
The organisms circulate carbon-di-oxide in carbon cycle by going through respiration, decomposition, sedimentation, and photosynthesis process but not ammonification. Basically the actual source of nitrogen is agricultural, when a plant or animal passes or an animal disperses waste.
In the remains, bacteria or fungi turn the organic nitrogen back into ammonium, a cycle called ammonisation or mineralisation. Then the micro-organisms generate metabolically required energy from organic nitrogen oxidation into ammonium. Ammonium is then essential for assimilation and absorption into amino acids or for use in other metabolic applications.
I am not entirely sure, but i think it would be the respiratory system because plants produce oxygen after taking in carbon dioxide, and that is similar to the human respiratory system. I am not completely sure though. hope this helps!
The answer is: massive stars create a lot of heavier elements. They produce much of the carbon and oxygen which is hugely important for humans and water respectively.
